DChalo Posted May 21, 2009 Share Posted May 21, 2009 Ok, so at the North Sulfur River there are these gray rocks, they are very fragile and crumble sometimes in your hands. Ok, so i have found an ammonite in one of these gray rocks but as soon as i held it, the rock crumbled and the ammonite was gone. Are these gray rocks the reason people come to the NSR after it rains? If they dont then why do they? Link to comment Share on other sites More sharing options...

DChalo Posted May 21, 2009 Author Share Posted May 21, 2009 Shale Can fossils be found in them? Will shale dry soon and not break? Link to comment Share on other sites More sharing options...
mommabetts Posted May 21, 2009 Share Posted May 21, 2009 Yes fossils can be found in it, When it drys it gets harder but will still break if you hit it right. Link to comment Share on other sites More sharing options...

LanceH Posted May 21, 2009 Share Posted May 21, 2009 The gray "rock" is shale which is really laminated clay. It can have a varying amount of clay content. Some shale can little clay and be powdery and disintegrate rapidly when wet. Some shale can have a lot of clay and be slippery and sticky when wet.

ShadyW Posted May 21, 2009 Share Posted May 21, 2009 that shale is extremely fissile. it's fissilitinessitude is legend aerie.(threw the "aerie" reference in for auspex) I've learned how to tell the difference between the thin fossil-bearing layer of clay in the NSR and the underlying fossil-free layer. The fossils provide the only friction available in either. I have never fallen on my so many times in knee deep water as I did trying to cross and re-cross 30' of the substrate clay as I did last Sunday! Sure, there was a strong current, but that gray clay is WAY more slippery than ice! Seriously, at one stage in my life I was going to be a ski pro, and I've ice skated, roller bladed and skateboarded all my life, and I've NEVER found it so difficult to hold my balance as I did on the gray layer of clay! Every complex scientific problem has an elegant and simple solution... and it is wrong. Link to comment Share on other sites More sharing options...
Oh-Man Posted May 21, 2009 Share Posted May 21, 2009 Daniel, Sounds like you re-learned that common lesson: "gravity is not your friend!" You'll need to get spikes next time... What is geology? "Rocks for Jocks!" Link to comment Share on other sites More sharing options...
